Have you heard of an “artificial” sun that is five times hotter than the star we finished circling around last week? New year, new science fiction, right? Except it’s not fiction.
Called the Advanced Experimental Superconducting Tokamak – or, simply “IS– China has launched an “artificial sun” which is in fact a nuclear fusion reactor. And this week it ran at 70,000,000 ° C for 17 minutes, according to reports.
“But why do we need another sun? Is the question you probably want answered. Well, the goal behind that is to be able to use nuclear fusion to harness “unlimited clean energy” by 2040.
“The recent operation lays a solid scientific and experimental basis for the operation of a fusion reactor,” Gong Xianzu, one of the managers of the experiment and researcher at the Institute of Plasma Physics of the Chinese Academy of Sciences. science. Recount The independent.

What Xianzu and other scientists hope is that the reactor will eventually be able to “mimic natural reactions that occur in stars like the Sun “to provide humans with an unlimited source of energy – just like the Sun – that can be controlled by humans.
Apparently, researchers have been trying to develop a functioning artificial sun for years. Another one achievement “stage” which preceded the latest development took place in May 2021, when scientists managed to operate the device at a temperature of 120,000,000 ° C for 101 seconds.
Today, the energy sector, globally, is largely dominated by fossil fuels, which is perhaps the Ithe biggest donor greenhouse gas emissions – aggravating global warming and contributing to climate change.
According to the UNDP, “Clean energy is a win-win solution to recovering from Covid19… The Covid19 crisis has accelerated the dynamic for healthier and greener cities. As the world urbanizes rapidly, energy efficiency in buildings, sustainable cooling and heating, smart city planning… are essential for the future of cities.
